CIE A Level Physics复习笔记2.1.5 Gradient of a Velocity-Time Graph
Gradient of a Velocity-Time Graph
- Acceleration is any change in the velocity of an object in a given time
- As velocity is a vector quantity, this means that if the speed of an object changes, or its direction changes, then it is accelerating
- An object that slows down tends to be described as ‘decelerating’
- The gradient of a velocity-time graph is equal to acceleration
Worked Example
What does the velocity-time graph look like for this acceleration-time graph?
